MARBLE-HANDLING MACHINE.

Application led October 28, 1921. Serial No. 511,083. l

To all 'whom t may concern:

Be it known that I, HENRY zen of the United States, and aresident of the city of Chicago, in the county of Cook` and State of Illinois, have invented certain new and useful Improvements in a Marble- Handling Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being vhad to the accompanying drawings, and to the numerals of reference marked y thereon, which form a part of this specification. y

Stone cutters, `when working on large blocks of marble or other bodies of heavy material, often experience considerable trouble in manipulating a block of marble to` conveniently position the different sur-l faces to be worlred on. i

This invention therefore relates to an improved type of a marble handling machine wherein a block of marble is adapted to be supported in slings from acircumferentially grooved cylinder or drum which may be manually rotated by gear mechanisms and a hand wheel to cause movement ofthe slings over the drum, thereby rotating the block of marble into any desired position of adjustment to facilitate working thereon.

It isan object of this invention to provide a machine whereby blocks of stone'may be conveniently turned to permit a stone cutter to have access to the diderent surfaces; or parts of a block of stone. f f

It is also an object of the invention to provide a stone handling machine wherein la large block of stone may be suspended and conveniently turned by operating a hand wheel.

Another object of the invention is rto provide a marble handling machine wherein a yolze suspended from a crane or other support has a grooved drum journalled therein for supporting a block of marble by means of endless slings, said drum adapted to be rotated by operating` a hand wheel and gears so that the slings will act to rotate the block of marble into dierent positionsso that the same may be cut .or carved.

It is an important object vof this invention to provide a 'marble handling ymachine of simple and' effective construction adapted to permit a block of marble to be suspended in endless rope slings from a grcoved drum which.: when rotated, will causeftipping of the block of marble into different positions CULI., a Yciti-v line 12e-12 of Fig. 8.

so that the same may be conveniently worked on by a stone cutter or carver. y Other and further important 'objects of this invention will be apparent from the disclosures in the specificatior` and the drawings. y

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. f vOn the drawings: v Figure 1 is a front elevation of a marble handling machine embodyingthe principles of this invention and shown supporting block of marble. f

As shown on the drawings: Y

rllhe reference vnumeral' l indicates a hook supported at one end of a hoisting chain 2. The chain 2 is carried by a crane, windlass or other suitable support (not illustrated).

The marble handling device comprises a yoke or frame embracing a beam 3 supported at the middle by apair ofbars 4. The bars 4 are bolted to the beam 3 and have the yupper portions thereof deflected inwardly toward one another and connected by means of a bolt 5,. aroundy which the supporting hook 1 is engaged. Inverted U- V et 6 is a bearing 9 secured in place by a bolt 10. A double bearing 11 is supportedrbetween the arms of the bracket 7 and is held in place by a bolt 12. J Rotatably supported by the bearings 9 and 11 isa shaft 13. Secure'don one end of the shaft 13v adjacent the outer end of the bearing 9 is a retaining collar 14. Keyed or otherwise seouredon the other end ofthe shaft 13 adjacent thefbearing 11- is a large gear 15 which is in mesh with a small gear or pinion 16 keyed on a stub shaft 17 supported in the lower portion of the double bearing 11. Keyed on the outer end of the stud shaft 17 adjacent the pinion 16 is a hand wheel 18. Pivotally mounted on one end of the beam 3 above the hearing 11 is a double pawl 19 having teeth 201'and 21"integrally formed thereon for coaction with the gear 1o.

. Mounted on the shaft 13 between the bearink's 9 and 11 is a drum comprising a wooden cy inder 22 provided with aY plurality; of spaced peripheral Vshaped'grooves 23. VThe ends of the cylinder 22 are beveled as at 24. Rigidly secured to each end of the cylinder 22 by screw bolts 25 is a metal end member 26 provided with a bevel surface 27 adapted to coact with the beveled surface 24'to afford a V-shaped groove. The drum end members 26 are keyed to the shaft 13.

Removably engaged in two of the drum grooves 23 are a pair of endless ropeslings 28adapted to support a block of marble 29.

FiguresV 8 to 14 inclusive illustrate Va modified form of a marble handling machine comprising a` lower bearing member or casting 30 cut away on both sides to form recesses at 31 and having integrally formed on each side thereof a' projection 32 and a side wall 33. The upper portion of the lower bearing member 30 is provided with a concave groove wherein'a strong steel main shaft 34 is seated. The shaft 34 is held in place by a grooved upper bearing member 35 which is bolted to the lower bearing member 30. Both end portions of the shaft 34 are longitudinally grooved to receive keys 36. -A collar 37 .is secured on the shaft 34 adjacent one end of the bearing 30-35 by means of a set screw 38. Secured on the shaft 34`adjacent the other end of the shaft bearing 30-35 is a large gear 39 held in place by a set screw 40.( Slidably engaged on each end of the shaft 34 and its key 36 isa pulley wheel 41 having a V-shaped peripheral groove 42. Each pulley wheel 41 is adapted to have engaged thereon an endlessrope sling similar to the slings 28 shown in Figures 1 and 2.

Both ends of a U-shaped strap or yoke 43 are engagedtinl the recesses 31 andl against thek projections 32 of the lower bearing member 30 and are secured in place by bolts 44.012 other. suitable means. Disposed longitudinally within the yoke 43 is an auxiliary or driving. shaft 45 the inner end of which is journalled in an opening in the Vlower bearing member-1 30. The outer end of the driving shaft 45 projects through the bight ofthe yoke 43 andhasaV chain pulley wheel 46 securedj on the projecting" end-` thereof. Secured7 on the driving-V shaft 45" adjacent the'inner side of theyok'ebight is a collar 47 held in place by a setscrew 48. Secured onthe driving shaft 45 adjacent the lower bearing member 30 is a pinion 49j which is in mesh with thelarg'e gear` 39; Rigidly secured kon each' side of' the lower bearing member on the wall`33 thereof, bybolts 50, is a' supporting strap or' bar 51, theends of which are deflected; The' upper? endsi-of the bars 51` are connected by a bolt? 52'to receive? the hook 53w which is attached -t'o' the end of ai hoisting chain V(not shown) The lower ends of the. bars all-are: c'onnectedby" a bolt 54. oni which ahook 55- is` engaged. Trained around thek pulley wheel 46 isa chain 56 adaptedtobepn'lledto cause rota tion of the pulley wheel'46i andthe driving shaft A45..

The operation .is as follows:

When .it is desiredtom cnt; or carve a block of marble the handling' machine is lowered by" meansof the chain 2`fwhic`h may beunwoun'd from a windlass or: lowered by other suitablen'iean's The two'A slings1-28 are then engaged around the block of marble' 29' and set in two of the drum grooves 23, as illustrated .inl Figure 1, the grooves* selectedl depending upon" the'v length ofV the-` bloclr29. The' chain 2Tv is'now elevated to.' raise` the marble block to a convenientl height to per'- mit a stone cutter; to work thereon; As the block 29 is lifted'off of the ground theel-ings 28 are tensioned and seat tightly in' the drum grooves.

lVhen it is desired to turn the marble block V29 from the full line position in- Figure 2 into'Y the dotted line position A,the hand-wheel 18 is'turned to the right thereby causing rota-tion of the pinion' 161 which in turn acts to' rotate the large'gear 1'5Vv and the drum toward the Vleft looking-if at Figure 2. The pawl 19 is thrown outwardlywith the tooth 21. clicking over thee-gear' teeth. When. the block 29 reaches'. pos'itio'nA.k and rotation of thehand'wheel'is stopped,A the pawl 19 ismaniuallythrown into the dotted linev position" of Figure" 7 and" falls by gravity with thetooth' 20'thereof' engaging between two of the teeth of the' gear 15', thereby lockingl said gear and the drum against further rotation toward the left. The marble block is tipped by meansof the rope slings 28 which seat tightly in the drum grooves and are rotated with the drum.

If the marbleblock is moved from the dotted line position B of Figure 2 intothe position A, the hand wheel 18 is manually turned toward the left looking at Figure 2, thereby causing the gear 15 and the grooved drum to be rotated in a clockwise direction. To hold the marble block 29 in position A, the pawl 19 is positioned in the dotted line position of Figure 7 and holds the gear 15 and the drum locked against a reverse rotation. Y

It will thus be seen that the large marble block 29 may be moved into diHerent positions by merely rotating the hand wheel 18. The gear ratio between the small gear or pinion 16 and the large gear 15 is such that one person may easilycause rotation of the block 29 into different positions to permit work to be conveniently done on all sides of said block.

In the modified form of the marble handling device illustrated in Figures 8 to 14Y the pulley Wheels 41. The two pulley wheelsv 41 are adjustable longitudinally on the main shaft 34 to permit blocks of marble of different sizes to be handled by the machine.

When it is desired to turn the block of marble the chain pulley wheel 46 is turned by pulling on the chain 56, thereby causing rotation of the driving shaft 45 and the pinion 49 mounted thereon. v The pinion acts to rotate the large gear 39 and the main shaft 34 on which the grooved pulley wheels 41 are adjustably secured. The pulley wheels 41 are thus rotated thereby causing the slings to be rotated to turn the block of marble carried thereby. The pull chain 56 is ,provided to permit turning of a block of Inarble when rin an elevated. positionl wherein it would be impossible for a person working on the block of marble to reach a hand wheel without lowering the entire device.

In caseit is desired to use the hoisting machine for elevating other' articles or devices, the lower hook may be used instead of the upper hoisting machine `hook 53 thereby making it unnecessary to remove the marble handling device from said hook 53.

I am aware that numerous details of con-y to cause rotation of saidA gear and drum whereby the slings act to rotate said marble block, andmeans on y'said frame adapted to engage said gear to hold the same locked against a reverse rotation in either direction.

2. An article handling machine comprising a frame having depending` ends, a drum between said ends and rotatably supported thereby, a plurality of endless rope slings encircling said drum, said drum ,havingk a plurality of V-shaped grooves therearound for the reception of and frictional engagement with said slings, the number of grooves being in eiccess of the number of slings to enable the position of the slings to be varied to suit the length of the article to be handled, and means for rotating said drum.

3. An article handling machine comprisking a frame having depending ends, a drum between said ends and rotatably supported thereby, an endless rope sling encircling said drum, said drum having a V-shaped groove therearound for a frictional engagement with said sling,y and means for rotating said drum.

4. A blockk handling device comprising ar frame, a drum rotatably supported thereon havingv a plurality of V-shaped peripheral,l

- grooves therein, endless rope slings engaged in said grooves adapted to carry a lock, and means for rotating said drum to cause said slings to rotate the block.

Intestimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
